Good evening, I wrote a very simple indicator on the job (attached file) I would like to clarify whether there is a way to prescribe in the code instead of a red and blue line (RSI2 and RSI3 in the picture (attached as well), respectively) was a single line - and it was red if RSI2>RSI3 and blue if RSI2 < RSI3

EMPTY_VALUE

Given N candles backwards. Find candles of size >= X pips, remember their number and the size of each one.

Add candlesticks >= X pips to the sorted array, then look for the place of the current candlestick in the array.

https://docs.mql4.com/ru/constants/namedconstants/otherconstants I don't really see howEMPTY_VALUE can help me. I have 3 arrays and each one gives out rsy if I set EMPTY_VALUE it just won't give me anything. my task is to write in the code instead of red and blue line the same line - and it will be red ifRSI2>RSI3 and blue ifRSI2<RSI3

Change colour as required to suit your needs

if(Open < Close) {
  SetIndexStyle(0,DRAW_LINE,STYLE_SOLID,1,clrRed);

Really?!))

Have you tried it?
